Serenbe’s “Hair” gets a new Berger and La Marquise du Châtelet continues to fight convention in a Weird Sisters’ staging. Also this weekend: The return of “Living Walls” street art and the Piedmont Park Arts Festival.

When Serenbe Playhouse begins its fourth season in June, it will do so with an eye toward change, according to Brian Clowdus, executive artistic director of the open-air theater company based in the Palmetto-Chattahoochee Hills area.
